_REF_EXTRA is only used in routine definitions, since it defines how
inherited keywords will be passed in (by value or by reference).
_STRICT_EXTRA is only used in routine calls, since it determines
whether the passed keyword names will be checked against the list of
accepted keywords in the called function. So _STRICT_REF_EXTRA would have
no purpose.
